What number could replace

below?`SYMBOL`

`\dfrac{`

`A`}{`B`} = \dfrac{`SYMBOL`}{`D`}

The fraction on the left represents `A` out of `B` slices of a rectangular `pizza( 1 )`.

init({ range: [ [0, 1], [0, 1] ], scale: [180, 25] });
rectchart( [A, B - A], ["#e00", "#999"] );

What if we cut the `pizza( 1 )` into `D` slices instead? How many slices would result in the same amount of `pizza( 1 )`?

init({ range: [ [0, 1], [0, 1] ], scale: [180, 25] });
rectchart( [0, D], ["#e00", "#999"] );

We would need `C` slices.

init({ range: [ [0, 1], [0, 1] ], scale: [180, 25] });
rectchart( [C, D - C], ["#e00", "#999"] );

`\dfrac{`

and so the answer is `A`}{`B`} = \dfrac{`C`}{`D`}

.`C`

Another way to get the answer is to multiply by `\dfrac{`

.`M`}{`M`}

`\dfrac{`

so really we are multiplying by 1.`M`}{`M`} = \dfrac{1}{1} = 1

The final equation is: `\dfrac{`

so our answer is `A`}{`B`} \times \dfrac{`M`}{`M`} = \dfrac{`C`}{`D`}

How many total slices would we need if we want the same amount of `pizza( 1 )` in `C` slices?

init({ range: [ [0, 1], [0, 1] ], scale: [180, 25] });
